TUBE workers are set for strike action in the new year in a bid to block bosses’ dangerous plans to sack 900 front-line staff, unions announced yesterday.

RMT and TSSA will stage a 24-hour stoppage from 6pm on Sunday January 8 in the ongoing row over ticket office closures and job cuts.

TSSA general secretary Manuel Cortes said: “Our members are fed up of being made scapegoats for passenger frustrations with the new — and failing — ticket-vending machines.”

RMT general secretary Mick Cash said the union would not stand by while safety is compromised on London Underground.

He said members had reported back on the “horrific” impact of job cuts and warned that dangerously overcrowded stations meant “it is only a matter of time before there is a major tragedy if we don’t act decisively.”
